Friends?

I have a friend and I'm not sure if she is flirting or not. Many people at school (I'm 15) have told me she likes me and we are both bi. I don't know what I should do because I don't want to ruin the friendship and I haven't come out to many people yet. She is always smiling and making eye contact. She also texts me a lot and want to be around me. Help please! Does she like me? Should I go for it?
